Runtime error when using nuget library: dependencies are wrong version

Description

Repro steps:
(0. Temp: Use https://github.com/jwittner/NuGetForUnity/tree/dev/versionRangeSupport to get around #379)

1. Use NuGet for Unity to get K4os.Compression.LZ4 (and dependencies)
2. Run your app

I see:

Assembly 'Assets/Packages/System.Memory.4.5.4/lib/netstandard2.0/System.Memory.dll' will not be loaded due to errors:
System.Memory references strong named System.Buffers in a different folder, versions has to match. Assembly references: 4.0.2.0 Found in project: 4.0.3.0.

and

Assembly 'Assets/Packages/K4os.Compression.LZ4.1.2.6/lib/netstandard2.0/K4os.Compression.LZ4.dll' will not be loaded due to errors:
K4os.Compression.LZ4 references strong named System.Runtime.CompilerServices.Unsafe in a different folder, versions has to match. Assembly references: 4.0.6.0 Found in project: 4.0.4.1.

Note: If I download those libraries (System.Buffers and System.Runtime.CompilerServices.Unsafe) from Nuget, it seems to work.
